document.write( "    Brine is a high-concentration solution of salt (NaCl) in water (H2O). In diverse contexts, \r\n" );
document.write( "    brine may refer to the salt solutions ranging from about 3.5% (a typical concentration of seawater, \r\n" );
document.write( "    on the lower end of that of solutions used for brining foods) up to about 26% (a typical saturated solution, \r\n" );
document.write( "    depending on temperature). Brine forms naturally due to evaporation of ground saline water but \r\n" );
document.write( "    it is also generated in the mining of sodium chloride.[1] Brine is used for food processing and cooking \r\n" );
document.write( "    (pickling and brining), for de-icing of roads and other structures, and in a number of technological processes. \r\n" );
document.write( "    It is also a by-product of many industrial processes, such as desalination, so it requires wastewater treatment \r\n" );

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In the course of water evaporating,  the process will go smoothly until the salt concentration will reach
\n" ); document.write( "the value of  26%,  approximately.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "At this point,  the brine solution becomes  SATURATED  and its concentration does not change any more.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The exceed mass of the salt will go as a sediment  ( ! not a mixture ! )  at the bottom of the reservoir.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The concentration of the salt in the brine will remain  26%.\r

document.write( "700-grams brine solution contains 20% salt by mass.\r\n" );
document.write( "\r\n" );
document.write( "    So, there are  0.2*700 = 140  grams of salt in the solution, at the beginning,\r\n" );
document.write( "    and 700-140 = 560 grams of water, correspondingly.\r\n" );

document.write( "ANSWER.  After 300 grams of water evaporated, the remained brine contains 260 grams of water and 91.35 grams of salt.\r\n" );

document.write( "         This brine is saturated at 26% concentration.  The amount of salt of 48.65 grams went from the original brine solution to the sediment.\r\n" );
